Evenly spread peanut butter onto half of the Ritz crackers. Sandwich with the remaining half of Ritz crackers.
Place the chocolate chips in a microwave-safe bowl, and heat in the microwave in 30-second intervals, stirring well until it is fully melted and smooth.
Using a fork, fully coat each Ritz cracker sandwich into the melted chocolate. Set them onto plates and decorate with the sprinkles. Let the chocolate sit until it is completely set.
